On Maciej's request and I also think this was one of the issues Boris
raised earlier I constructed the following testcase:
http://tc.labs.opera.com/apis/XMLHttpRequest/open/024.htm
Most browsers seem to throw at some point, but they are not really
consistent. The testcase works as follows. You have a parent browsing
context A and a child browsing context B. The initial situation is that A
holds document 1 and B holds document 2. When 2 is loaded 1 invokes the
XMLHttpRequest constructor of B and then causes document 3 to be loaded in
B. When document 3 is loaded 1 tries to initiate a request.
Internet Explorer 7 seems to throw when after 3 is loaded 1 invokes
open(). Opera 9 seems to throw at the same stage when send() is invoked.
Firefox 2 seems to invoke frame.contentWindow.client() when it shouldn't.
Not sure why that happens.
Open questions are:
1. What happens if you navigate from 3 back to 2.
2. What happens if the base URI "essentially" stays the same.
(No "directory" changes.)
And more I assume :-(
Also, is there any particular desired behavior for these cases?
(The testcase mentioned is work in progress.)
